Silicone Chemistry
Silicones are synthetic polymers formed from quartz sand (silicon and
oxygen) and other products of nature, and uniquely able to withstand nature’s
many extremes.
Silicones are the “missing link” between organic and inorganic
chemistry.
Silicones have unique properties other polymers cannot match.
By changing the size or structure of the silicone molecule or by adding
different compounds to it, you can enhance or change the way it behaves.
The secret to silicone’s amazing capabilities lies in its flexible Si-O-Si
backbone.

Improving the Quality of Our Lives
Silicones enable the design of thinner, smaller, faster electronic
devices.
Silicones make our cars safer, more reliable, and less costly to
maintain.
Silicones make our homes and offices safer, healthier places to live and
work.
Household appliances manufactured with silicones are more dependable and
require less maintenance.
Silicones protect power transmission equipment from environmental damage and
help keep the electricity flowing.
Silicones enable address labels to peel off easily and industrial tapes to
stick tightly to difficult surfaces.
Silicones make towels fluffier and more absorbent and help protect skiers
from injury during a fall.

An
Amazing Range of Capabilities
Silicones are a huge group of products that happen to share some very useful
traits ... like stability at high temperatures and resistance to age, sunlight,
moisture, temperature extremes, and chemicals.
Silicones can take many different forms and perform hundreds of different
jobs.
Silicones can be hard and brittle, or soft and flexible.
Silicones can be liquids or solids, durable or temporary.
Silicones can adhere or release.
Silicones can be hydrophobic (repel water) or hydrophilic (absorb
water).
Silicones can make things soft, smooth, and silky or hard, rough, and
tacky.
Silicones can destroy foam or stabilize it.

Proven Performance
Structural silicone sealants installed in buildings around the world in the
1980s are still performing today.
Approximately half of all makeup, hair and skin care, and underarm products
introduced today contain silicone.
Silicone finishes are widely recognized as the best materials for increasing
the softness of fabrics and enhancing the way they feel.
Silicone defoamers have been used extensively in pulp washing operations
worldwide since the early 1990s.
Virtually any electronic device that is powered by batteries or electric
current relies on silicones.

Competitive Advantages
Silicones perform under conditions that would defeat organic (carbon-based)
materials, are more effective at lower levels, and provide unique solutions to
difficult problems.
Silicone architectural coatings typically last twice as long as acrylic
coatings, and silicone building sealants typically last three times as long as
urethane sealants.
High-voltage-insulator silicone coatings perform for 10 years or more, while
some other protection methods must be reapplied every 18-36 months. Imagine the
long-term cost savings of silicone.
A silicone antifoam that costs twice as much as an organic antifoam can
actually cost half as much to use.
Adding as little as 1.1¢ worth of silicone to a typical 300-gram
hair-conditioning rinse doubles dry combing benefits and increases shine by
20%.
A single silicone paint additive can provide as many as five different
performance benefits.
A specially formulated silicone release coating system lets label
manufacturers reduce their coat weights as much as 15-25 percent and use
lower-cost base papers.

Safety, Sustainability, and Resource
Conservation
Silicones have been used safely and successfully in personal care products
for more than 30 years and have been the subject of more than 5,000
studies.
In the environment, polydimethylsiloxane fluid breaks down into water,
carbon dioxide, and minerals already found in the earth’s crust.
If an organic sealant needs to be cut out and replaced every seven years,
the amount of garbage produced and solvents used will be at least three times
greater than if a longer-lasting silicone sealant had been used.
Many silicone fluids and elastomers can be recycled.
Silicones help manufacturers eliminate water-wasting process steps and
reduce the use of air-polluting solvents.
Silicones help automakers comply with an entire alphabet of environmental
laws and regulations ... RoHS, EPA, CARB LEV (Low-Emission-Vehicle), WEEE, Euro
4, Euro 5, EU law 1999/13/EC, and more.
